To all whom it may concern:

Be it'known that I,Lou1s Bmnro'r, en-' 'gineer, citizen of the French Republic, re-

' fication.

siding at Suresnes, Department of Seine, France, have invented certaln new and use ful Improvements in Compressed-Fluid Dis-' tributers, of which the following is a speci- The invention relates to compressed fluid distributers; and it relates more particularly, among the apparatus of the kind in question, to those that can be utilized in the apparatus for starting explosion engines.

i r It'consists chiefly also-at the same time a It has for its chief object to make the ap- 5 paratus of the kind in question so that they should work better than those hitherto designed.

as in building the apparatus of the kind in question so that they should have a long1- tudinally moving pistonin addmg to the said piston such means that, when the said 'piston arrives at the end of its working stroke, the said means should occupy such a position, as to bring about simultaneously the shutting oil of the admission of the compressed fluid to the operative face of'the pis ton, and the opening of 'admlsslon oi the said compressed fluid to its other race, so that the said piston returns to its lnitlal position, the said means remaining then in the position which they occupy, aslong. as the l compressed fluid inlet conduit remalns open.

Apart from this chief arrangement, it comprises certain other arrangements, more explicitly referred to hereinafter.

It relates more particularly to certain methods of carrying out, aswell as of applying, the said arrangements, and'more particularly still, by way of*new industrial products, to apparatus of the kindin question comprising application of the same ar-' "rangements, to special elements suitable for I apparatus..

building them, as Well as to explosion e'ngines which are started'by means ofsuch And it will-be in any case clearly understood from the"following"description, aswell as from the accompanying drawing which, of course, is given merely by way of vexample. v A I The single figure of the said drawing "shows, in "axial longitudinal section,"a compressed fluid distributer according to the invention applied to the starting of an explosion engine.

which refers more particularly the drawing,

According to the invention, and morepan' tlcularly according to that of the methods of V carrymgI-itout, as well as of applying it,"tc

when it is intended to builda compressed it should have a rod 6 secured to the metal fitting, arranged concentrically with suitable forstarting an "exthe cylinder a, the said rod 1) being constituted by a metal tube of circular cross-section;

end of the rod bprojecting' from one of the cylinder ends when the piston is'at the endofi'ts'return stroke toward the other end, a

cap 6 in the form of a cup, the said cup being provided in the portion of its bottom situated around the rod 6, with openings 6?? and being so secured to the 'saidrod b that its edge should be in line with the cylinder a.

On the end of the cylinder, facingthe cap 6 is screweda' cover a adapted to guide'the rod- 6' of the piston; the said cover is p vvided with openings a 9, andthe rod 6' is made of such length that when the cap 5 i is in contact with its edge with the cover a, the piston" b is at thebottom of its stroke toward the other end of the cylinder a.

ting.

centric with the rod 6, the said rod (3: being andso that it should have, secured to the This'main piston structure hasf'a' supple mental piston 0 adapted to move in the in! terior of the rodb, and the s'aid p'iston cis preferably constituted' by "means of t-wo" stamped outleathers inclosed in a metal fit The piston 0 iscs'ecur'ed to a rode con constituted byatube of circular cross-section of an outside diameterperceptibly smaller than the inside diameter of the rod 1).

The rod 0 in advance of the front face of the piston c, has secured thereto a cup 0 of an outside diameter slightly smaller than the inside diameter of the rod 6, and the said rod 0 is provided between the front face of the piston c and -'tl1e*cup 0 with openings 0 Into the interior of the tube 1), and begin- 7 ning with its free end, is introduced the structure just described, starting with the than the inside diameter of the said tube 0 one of the ends of the said tube (Z is connected to the opening0 and its other end is madeto open at the face of the piston c.

opposite the bottom of the cap 6 On the end of the cylinder a is screwed a cover a having a central cylindrical hole a with a seat adapted to receive a valve, and at a suitable point another hole is formed and provided with a seat for another valve.

The tube 0, is threaded and therein is secured a tube 0 of a diameter smaller than the diameter of the hole a, and has at its outer extremity a valve 6 .adapted to engage with the seat of the hole a4, a springe having been previously inserted between an in wardly projecting central terminal Wall of the cover a and the valve 6. The free end of the said tube 6 is caused to rest in a recess a" provided in'an outwardly projecting central endwall of the cover the said recess comprising a seat adapted to cover a part 6 of the rod 6 forming .a valve.

At the end of the rod cand on the rod 6 is secured a rod f, to the end of which is fitted a rod 7" secured to a valve 7 adapted to engage with the seat of the hole a 1 lVhen the piston b is at the'end of its return stroke, the valve. 0 is away from its seat, and the valve 7? is held in contact with its seat. I I I Moreover, the rod 0 is provided with a stop 9 with which engages a finger g mount-,

ed on a. spring bladeg secured to the cover a 7 To the, shaft 'Z of the engine which is to,

i be rotated orto anintermediate shaft com municating its movement to the engine shaft,

' is secured a ratchet wheel 7'; with the said ratchet wheel engages a pawl y" which is pivoted at a suitable point of the lateral face the said shaft 2', and the pawl j is connected by cable m passing over the groove of the pulley 7a to an attaching flange 19 secured to the bottom of the cap 6 the said flange 6 being preferably cast together with the said cap 6 In the same way, the pawl y" is connected to a cable a wound in the direction opposite to that of the cable m in the groove of the pulley 7c; the cable a being caused to pass over a guide pulley a, then through the interior of a tube 0, which is arranged parallel to the axis of the cylinder a, along the latter, the said tube being suitably guided along thevcylinder a, and connected at one of its ends to vthe flange 6 and cable a being secured to the other end of the tube 0.

The operation of the improved mechanism in starting an explosion engine therewith is as follows The various parts being inthe position shown, a compressed fluid, for instance air, is admitted through the conduit h and the hole @6 into the cylinder a, and. exerts a pressure against the piston Z) and also passes through the opening 0 into the tube (Z, and also exerts a pressure on the central portion of the cap 6 The piston 7 will return. to its initial position in the following manner; 3

A short time before reaching the end of its working stroke, the piston I) through its leathers 6 engages the edge of the cup 0 and produces a movement of the rod 0, and

the stop g is released by the locking finger g The valve 6 then engages with the seat of the hole a the end of the rod 6 being disengaged from therecess o the Valve is moved simultaneously away from its seat,

and the interior of the cylinder at is opened to communication with the atmosphere in the cylinderin advance .of the piston 5 escapes outward, and the air containedbetween the piston c and the bottom of the cap 6 gets into the cylinder a through the tube d Under these combined actions, the piston Z) will be moved in the through the hole a-, andthe air contained.

in order also to escape outward through the hole a During this time, the compressed air admitted through the conduit 7, gets into the interior of the tube 0, through the tube e, escapes through the openingsc? and acts on the central portion 'ofthe piston 6, comprised between the tube 6 and 0', the-piston b returns gradually back until it reachesthe V end of thestroke, driving with itthe tube 0 so that the pawl j returns to the position apparatus to work again, it is necessary to 4 comprising a cylinder having a main piston i work again,

move the valve 6 away from its seat; it is suflicient for the purpose to closethe conduit h, the equilibrium is then broken by the spring 6 the rod 0 is shifted, and the finger g engages over the stop the valve e is moved away from the seat, the valve e is pressed against its seat, the valve f closes the hole (0 and to make the apparatus conduit h. It goes without saying that the invention is by no means limited to that of the methods of carrying it out, of applying it, which has been particularly described; it comprises on the contrary any modifications.
